[LTP] [PATCH v3] mpls01.sh: Add --allow-unsupported for modprobe

[Petr Vorel]

Hi Wei,

> In sle-micro we encounter following error when do modprobe:
> root# modprobe mpls_router
> modprobe: ERROR: module 'mpls_router' is unsupported
> modprobe: ERROR: Use --allow-unsupported or set allow_unsupported_modules 1 in
> modprobe: ERROR: /etc/modprobe.d/10-unsupported-modules.conf
> modprobe: ERROR: could not insert 'mpls_router': Operation not permitted

This is needed in other mpls tests (mpls0[2-4].sh, it needs to be in mpls_lib.sh
to be reused.

Kind regards,
Petr
